Verify a MoltGuard Verifiable Credential JWS signature.
AI agents call moltguard_credential_verify to retrieve information from MolTrust MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Verification of a JWS signature is a pure integrity check that retrieves and validates credential metadata without altering state, creating resources, executing code, or moving funds. This is a classic Read operation.
From the tool's definition Tool description states 'Verify a MoltGuard Verifiable Credential JWS signature' — verify is a read-only cryptographic check operation with no side effects, no data modification, no execution of arbitrary code, and no financial impact.
